It depends upon the season...

Deer are foragers, basically goats with antler, the list of what they will not eat will be shorter than what they will eat....

They dang sure love white oak acorns, but can't eat them until they fall, same with beech nuts and apples....Honeysuckle is an over looked food by many deer hunters...On our farms, peanut vines get hammered during the summer as well as soybean plants....Cut corn is very good, but they seem to prefer soybeans that are still green over cut corn....

During bow season (September) we have a grove of persimmon trees that are a deer magnet, on another farm its grapes...

You need to keep up with the food that they are currently preferring....
